A tank includes a container for accommodating an ink, a removal preventing pawl which is provided at a rear surface of the container and engaged with a tank holder and a latch lever which is provided at a front surface of the container opposite to the rear surface so as to be elastically displaced and which has a latch pawl engaging with the tank holder. The height of a rear wall of the holder to which such tank is mounted is set to be lower than the height of the tank. The height of the side surface of the holder corresponding to a side surface of the container is set to the lower than the height of the liquid tank. Thus, the container abuts the upper end of peripheral wall of the tank holder to be rotated about this upper end so that a part of the side surface of the container is protruded externally of the holder. The container can be removed from the tank holder by using such rotational operation. In accordance with this holder, a space required for removing the container from the tank holder is placed external of the peripheral wall of the tank holder. Thus, a waste space ensured within a conventional tank holder in order to remove the liquid tank can be eliminated.
